日本語
STEIN is a quality inorganic soil hardening agent that is environmentally friendly. The formula was developed in 1975 by a Japanese company named Matsumura Synthetic Laboratory Co., Ltd. Now in its 40th year, STEIN continues to be utilized by a handful of public work projects such as roads and irrigation for more than 1,500 places. It was adopted not only in Japan but also in countries such as Taiwan, Malaysia, Indonesia and the United States.
Using STEIN is very simple. The process involves mixing on-site soil with an appropriate amount of water and STEIN agent. Through a chemical reaction known as Pozzolanic reaction and hydration, the soil hardens into a strong and solid mass. Known for its durability and reliability, projects treated by STEIN can definitely stand the test of time. With its low cost, simple construction and eco-friendly formula, STEIN is the way to go.
How It WorksHere are top 3 reasons why you should consider choosing STEIN
With Stein's fast acting mix, the road is serviceable for all road vehicles in just 24 hours upon completion of treatment.
The simple construction entails low cost. Its components are 95% Portland Cement and 5% Stein element.
For 40 years, STEIN was adopted for public work projects such as roads and irrigation for more than 1,500 places. The STEIN ingredient can stand the test of time with a highly reliable service life as that of a concrete.
The in-place soil investigative test
Some of the placesout of 1,500 constructions all over Japan and other countries such as Taiwan, East Timor, Indonesia, Philippines and more.
Many rural roads were constructed by STEIN in 1970s (Asahikawa, Hokkaido). It is also used in the character of channel.
The sludge-like riverbed was formed of soil hardening agent "STEIN" in 1980s. (Keelung River, Taiwan)
The joint research on anti-burst measures for agricultural pond with Japanese MAFF NIRE (National Institute for Rural Engineering) is under way.
